Haven’t visited TTAC in a while but I’m back! My Mazda 6 has now crossed the 101k mileage marker and all your nuggets of wisdom have helped keep this classic functional and beautiful. However, there’s another problem rearing its head that has plagued even the Mazda forums I’ve visited for a resolution.

It involves the car’s driveability at anything below 3000 rpm. Doesn’t matter whether the engine is just warming up or at operational temperature, the car will hesitate (sometimes violently) in a stuttering/bucking fashion when accelerating from a stop through the gears until I crest that magic 3000 mark on the tach. Out on the highway, passing in top gear is almost impossible because of the engine’s hesitation if revs fall below that number, requiring a downshift to 4th to keep them up. At first I thought my manual skills were to question but then I never started experiencing this issue until around the 87,000 mile mark. It has since gotten worse. Sometimes the bucking is enough to trigger the CEL but then it always goes away after a while.

Browsing the forums I’ve tried everything from cleaning the MAF sensor, fuel injector cleaner, throttle body cleaning as well as replacing the O2 sensor. I’ve narrowed it down to either spark plugs (some forum members replaced theirs but the problem came back hours later), the coils or possibly a vacuum leak. One post I read indicated a potential cylinder misfire. Even Mazda dealers were confounded. (Read More…)

Power and weight figures for the 2015 Ford Mustang have been released, and while the 5.0L Coyote V8 gets a nice bump in power, the V6 gets dialed back a bit, to help put some distance between it and the new Ecoboost 2.3L engine.

With the closure of Japan’s last operating nuclear power plant hitting the news over the weekend, people asked me what that means for Japan’s auto industry. My answer: Nothing. The shutdown of the first nukes on March 11 a year ago was much more dangerous than the long scheduled downing of the last. Nissan’s Carlos Ghosn sees a much bigger danger: the power of the yen. The high yen at the currency exchange. And higher yen numbers on the electricity bill. (Read More…)

Suzuki is not buying into the „once in a millennium tsunami.” Suzuki has a lot of its production near the waterfront in Japan’s Tokai region. Scientists give the area between Toyko and Nagoya an 87 percent chance of getting hit by an earthquake with a magnitude of about 8 within the next 30 years. Suzuki’s answer: Let’s get out of here, fast. (Read More…)

According to The Nikkei [sub] “Toyota Motor Corp. said Wednesday it will start offering on Thursday a free application for smartphones that sounds an alarm if the user’s home electricity use reaches a preset level.” Don’t believe it. The Nikkei made it up. (Read More…)

Japanese carmakers are battling the power shortages after the March 11 tsunami. Often, they are asked why they didn’t move more of their production abroad, like to China. A lot of them did, only to face bigger power problems in China. China is heading for what Reuters calls “its worst power shortage since 2004.” While the lights stay on in Japan, cities in Southern and Eastern China have regular blackouts. (Read More…)
